The Great Wall of China, one of the world's most iconic structures, winds through mountains and deserts, stretching over 21,000 kilometers.

About this subject

The Great Wall of China is not a single continuous wall but a collection of fortifications built over centuries by different dynasties. Construction began in the 7th century BC during the Warring States period and continued through the Ming dynasty (1368-1644). The main purpose was to protect the Chinese empire from invasions by northern nomadic groups such as the Mongols and Turks.

The total length of all sections of the Wall reaches approximately 21,196 kilometers according to official 2012 measurements. This distance includes both built walls and natural barriers like trenches and rivers that formed part of the defensive system. The average height of the wall is 7 to 8 meters, with some watchtowers reaching up to 14 meters.

The Great Wall was designated a UNESCO World Heritage site in 1987, recognized as one of the greatest engineering achievements in human history. Contrary to popular belief, it is not visible from space with the naked eye, a myth that has persisted since ancient times. The most famous and best-preserved section is at Badaling, near Beijing, which receives millions of tourists annually.

Interestingly, the Wall was not only built with stone and brick but also with tamped earth, especially in the arid western regions. During the Ming dynasty, bricks and stones were used to reinforce sections near the capital. It is estimated that millions of workers, including soldiers, peasants, and prisoners, participated in the construction over the centuries.
